DD stopped drinking from a bottle at 12 months, I transitioned her to a Nuby sippy cup with the softer nipple. Last night I tried to give her a sippy cup with the hard nipple but she will not suck the hard nipple so that the milk could come out. She then cries for her other cup. I know it probably will take time, but I just am not sure how to go about it.
Should I rotate cups?
Wait it out?
Any suggestions are appreciated. TIA!
